i .Be-itknown that I, VVILLIAI C. jrn`vnNs,

a citizen of the United States, and allresident of the city-of Akron, inthe county of Suininit and State of Ohio, h-ave invented certain new anduseful Improvements in Folder -Devices for lVrap'piiig-Machines; andvIdo hereby declare'that the following is a full, clear, and exactdescription ,o f the same, 10 reference being had tothe accompanyingdrawings, and to the .numerals of reference marked thereon, .-which forma part, of this 2,0 which'forins Aa part of a Wrapping machineforappli'fing aj'spiral wrapping or Winding oi'. coveriiig strip such aspaper aboutv annular'bodies for example automobile tires, .coiled vi reandthe like, or upon long cylindricalbodies such as pipe, rods, or otherobjects capable Lof receiving such a Wrapping;

It is an object of this, invention yto conl struct a folding device usedin combination with a creasing rollerwhich acts to crease the strip ofpaper drawn through the folder, 'creasing the same as it is led aroundsaid "roller, the roller of course permitting the strip to leave theshuttle for application to the articleatf'any angle for differentrelative positions'of the shuttle and the article with- '-out requiringreadjustment of the parts'.

It is also anobject of this invention to `construct a'folder devicewhich is pivotally mounted adjacent a creasing roller adapting 40 thepaper' wrapping to be drawn through' 'tail 10.y of' said detent'leverextends aroundl the folder device and creased upon the roller and thenled to fthe article to be' wrapped.

It is furthermore anobject'of ithis inven-I tion to construct animproved form of folder 1:5 device which co-'acts with aspring `plate toafford a tension mechanism for' the'paper drawn through the folde-i`before` being folded;

" It'isnally an important object of this invention to construct a devicesimpleinfconstruction and operating veflicientlv to perform the purposefor which it is designed. The invention (in a preferred form) isillustrated in the drawings and hereinafter more fully described.

The niaiiisectioii of theshuttle,'which is:

a lclosedI ring when in condition for operation, is denoted as awholebythe .refer-1 ence numeral 1,'and hinged thereto is asecvt-1on..2, to permit opening of the shuttle for insertion or removalof .the varticle to be wrapped."` ,Said .hinged section *2, is piv-ftions jl, onbothsides thereof forming a yoke adapted to receive thereina tongue ineinher 1.- A pin 5, extends transversely lthrough saidlprojections 4, and is jadapted to `holdy .the ends of the 'shuttlesections engaged ywith one anotlier, thus insuring 'a true`pe" vripheryfor the shuttleunder all conditions when the hinged'section is closed'.l V Means are provided 'for `^locking` said hinged sectionjinclosedpostionl I For this -purposefa notch Slis provide-.din the shuttlel,on the inner periphery' thereof, "and piv-Y 90 otallv supportedl bvmeans of1a-bolt'7g'exl 5^; tending radially from the inner sidefinto.said hinged section Q; ofthe 'shuttleis a swinging detent 8, having"afinger 9"adapt-F ed to engage in said notch.

Then it is `desired to ref of the detent lever` thusreleasing the lock; ingcnd ofjsaidv detent leverrwhereuponQthe saine maybe swung laterally, carrying the finger 9, thereon,'out of the/notch 6,and past no mitting the shuttle to be opened. Mounted i aglip 21,integral with the outer foldand. turnedl'over the inner fold. Theopposite. end of said'nozzle is wider and fla-ring to' receive the paperorother material therein. Said nozzle is secured on said bracket plate17, in'any suitable manner with .the tapered end of thel nozzle directedoutwardly. Mounted adjacent said tapered-end of the l foldingl deviceand set in the faceof the shuttle isa stud shaft 22, which is inclinedslightly, as shown in Fig. 3. The lower end .23, of said stud shaftengages perpendicnilarly through thewall or face of the shuttle,`

anda nut 24, is provided thereon, which 'may bel loosened to permit anadjustment of the upper angled -portion 22, into any desired position.Journaled onl said stud shaft 22, is a roller 25, orif preferred, the'.

stud shaftmay ,be' merely rounded or provided with a convex, surfaceover which the paper or other wrapping material may be drawn to thearticle to be wrapped. .A

washer 26, the opposite surfaces ofl which.

are inclined conforming to the angularity of the portions 22 and 23, ofthe stud shaft, is engaged upon said stud 'shaft between said roller 25,and theface of the shuttle.

The operation is as follows:

The paper or other wrapping material is drawn from the reel through thefolding nozzle 19, around the guide roll 25, and thence to the article,and when the shuttle is rotated of course the wrapping material isappliedv to the article. The pivotal l mounting of the folding nozzle19, by means of the bolt-18, on the face of the shuttle, permits thenozzle to properly7 aline itself between the roller 25, and theperiphery of the constantly decreasing reel of paper 1G. As clearlyshown in .F ig. 4., at the entrance end ofthe'folder nozzle the innerfold plate vover which the lip 21, extends, is rounded at its endbeneath the -Haring epfl of the upper fold of the plate, so that an easyeutrance for the wrapping material is pro The roller 25, may be adjustedinto "'itions by loosening the nut 24, se oper operating position of theith respect to the article being rol-ler :25V W wrapped'may be easilysecured.

I am aware that various' details y-efcon d struct-ion may bevariedthrough' a .wide

range without departing fromthe principles 'of this invention,.and Itherefore do not' purpose limiting the patent granted otherwise thannecessitated by the prior art.

I claim as .my invention: i

1. The combination withv a shuttle and paper carrying means thereon, o'fa 'folder device pivotally mounted-upon. said shuttle, and an adjustablecreasing memberadjacent thereto to crease the folded paper leaving saidlfolder device. j

2. In adevice of the cla-ss described. the combination with a shuttleand paper carryingv means thereon, of a movably mounted folder device.and an adjustable rotatable creasing member for the paperfolded by saiddevice, said folder device adapted to lautomatically aline itself inposition between said creasing, member and the paper carrying means asthe direction of feed of the paper from said means varies.

3. In a device of the class.. described the combination with a shuttleanda paper feedA ing lmeans thereon, folding mechanism to 'fold thepaper led from said means, and an adjustable-.creasing member inclinedat an angle with respect to the surface` of the shuttle to crease thefoldfin the paper, said folder mechanism so constructedas to antolimatically aline itself into proper position between said means andmember as the direction of feed of said rpaper changes with a decrease1n the supply thereof.

4l. In a device of the class described the' combination with a shuttleand a paperfeeding mechanism, of a pivoted folding device for said'paper mounted to automat` cally adjust itself to said mechanism as thedirection of feed of the paper to said device. varies. i

5. 'In a device of the class described `the combination with a shuttle,of a paper folding device pivotally mounted thereon, and a rolleradjustably mounted in an inclined position on said shuttle adapted tocrease the folded paper proceeding from said folder device andled to anarticle being 6. In a device of the class describedthe combination witha shuttle, of lnu-hanism movably mounted thereon acting autoinaticallyto aline itself with the line of feed of paper fed therethrough and tobe folded thereby.
